# DOMStringList

`public interface DOMStringList`
``

org.w3c.dom.DOMStringList

The `DOMStringList` interface provides the abstraction of an ordered collection of `DOMString` values, without defining or constraining how this collection is implemented. The items in the `DOMStringList` are accessible via an integral index, starting from 0.

See also the Document Object Model (DOM) Level 3 Core Specification.

## Summary

### Public methods
`abstract boolean` | `contains(String str)` Test if a string is part of this `DOMStringList`.
`abstract int` | `getLength()` The number of `DOMString`s in the list.
`abstract String` | `item(int index)` Returns the `index`th item in the collection.

Returns

### getLength
